Cut .034 off the block (zero deck). Then run .036-.039 gaskets.
Yes, it will increase compression, but the added turbulence from the "squish" benefits you MORE in both WIN/WIN categories. Power production AND detonation prevention. Then, do some bowl work on the heads to unshroud the valves and add a few cc's to the chambers. Don't cut the heads unless they arent straight/flat. I can't tell what carb that is. Since you're running an aftermarket distributor, figure out your electronic advance and lock out the mechanical advance. What ignition box/amp are you gonna run? |

So I couldn't run a smaller gasket with the way the block is now and ignition is just factory setup still

Thank u smitty that's what I thought but wasn't positive

Only issue with the .027" gasket is your still going to be above recommended max "quench" distance of .045". Unless you're going for every last ounce of performance in a timed racing situation I doubt you'll ever be able to measure the difference it power.
